Window mastic in Netherton, done properly
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. We work on aluminium frames, composite doors and uPVC windows, and common reasons people get in touch are water coming in at the bottom corners of a door and a bead that doesn’t match the frame.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Every job is covered by our one-year guarantee.

Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
What affects the quote in Netherton
The quote reflects the job in front of us. We look at:
- How much there is to do
- Mould in or behind the old joints
- When we can work, for business premises
- Access and height
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What to tell us for a quote
When you contact us, it’s useful to know:
- Where the job is, and your postcode
- What’s wrong with the joints now
- The rough size of the job
- A few photos by email, if you can
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, email us at info@mrmastic.co.uk.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Common problems we fix in Netherton
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Keep an eye out for these signs:
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- White mastic on grey or black frames
In and around Netherton, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Common questions in Netherton
Can you do window mastic in Netherton?
Yes. Our work covers the whole of Scotland, and Netherton is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will you come out to Netherton?
Yes. Netherton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for letting agents?
Yes, often. Several properties can go on one quote.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you reach windows above the ground floor?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
For anyone letting property in or around Netherton, several properties can go on one quote. Just tell us the addresses and what each one needs.

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Outdoor work around Netherton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints

Related advice
Window mastic in Netherton: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Homes close to Netherton Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why act early in Netherton
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Around Netherton, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
